摘要：
NiAlCe-LDH were prepared by co-precipitation method and modified with DBD plasma to improve the photo catalytic performance. NiAlCe-LDH were analyzed by XRD, EDS, XPS and UV-Vis characterizations, and evaluated by methyl orange degradation under ultraviolet light irradiation. NiAlCe-LDH photocatalysts exhibited good photocatalytic activities. NiAlCe-LDH with Al3+/Ce3+ molar ratio of 0.035/0.015 showed nearly 100% MO degradation within 48 min when the MO concentration was 80 mg/L and the catalyst addition amount was 1 g/L. NiAlCe-LDH modified with DBD plasma at 70 V for 20 min exhibited improved photocatalytic activity, nearly 100% MO degradation within 36 min. LDH modified by DBD plasma with improved photocatalytic performance had broadened new horizons for photocatalytic field.
